4.0 INSTALLATION
4.1 Preparation of Substrates:
The substrates to be covered must be free of all grease,
oil, loose particles, moisture, and other foreign materials.
Areas not receiving a foam plastic insulation application
must be masked off or otherwise protected from overspray.
The application of primers, when used, must be in
accordance with the spray foam roofing manufacturer’s
installation instructions.
4.2 Substrates:
4.2.1 Combustible Substrates: Combustible substrates
15
/32-inch-thick (11.9 mm), codemust be minimum
complying, exterior-grade or Exposure 1 plywood (US
DOC PS1). All plywood edges must be supported in
accordance with the requirements set forth in IBC Section
2603.4.1.5.
4.2.2 Noncombustible Substrates:
4.2.2.1 Cementitious Substrates: Structural concrete
substrates must have a minimum compressive strength of
2500 psi (17 237 kPa). Cementitious decks must be
thoroughly cured and must be subjected to specialized
treatment, such as wire brushing or commercial
sandblasting, or must be chemically cleaned to ensure
adequate bonding.
4.2.2.2 Metal Substrates: Minimum No. 22 gage
galvanized steel [0.030 inch (0.76 mm)] deck. Metal decks
must be cleaned of any adhesion inhibitors, and gaps in
end or sidelaps must be sealed with an approved sealant.
4.3 Roof Slope:
The polyurethane foam plastic insulation must be sprayapplied to form roof slopes that have a minimum slope of
1
/4:12 (2 percent) and a maximum roof slope as specified in
Table 1.
4.4 Foam Plastic Insulation Application:
The polyurethane foam plastic insulations described in
Section 3.2 are applied at a 1:1 ratio by volume of the A
and B components to one of the substrates described in
Section 4.2, using foam-spraying equipment and
processing
parameters
recommended
by
BASF
Corporation. Application of the foam plastic insulation must
be performed when the following conditions are met:
 Substrate temperature is at least 50°F (10°C);
 Ambient temperature is at least 50°F (10°C);
 Relative Humidity is below 85% RH;
 Dew point is more than 5°F (2.8°C) above or below the
ambient temperature;
 Wind speed is equal to or less than 15 miles per hour
(24.1 km/h). Wind barriers are needed when the wind
speed is greater than 15 miles per hour (24.1 km/h).
When conditions are outside the parameters noted
above, consult BASF Corporation for additional guidance
prior to installation.
The foam plastic insulation must not be applied to wet
or damp substrates, or when dew, condensation,
precipitation, or freezing temperatures are expected prior
to completion of the foam and coating application.
Foam plastic is applied in maximum 2-inch-thick (51 mm)
passes, to reach the desired thickness as noted in Table 1.
The total finished thickness must be achieved within the
same day. The finished surface of the foam must be
smooth and free of voids, pinholes and crevices.
4.5 Application of Coating:
The foam plastic insulation surface must be dry and free of
all damaged foam, dirt and foreign material before
Page 2 of 3
application of the coating. If the insulation surface is
damaged to the point where cracks, voids or large
depressions appear, additional insulation must be applied
to create a satisfactory surface. After the insulation has
developed sufficient strength to support foot traffic, but
within 72 hours, the coating must be brush-, roller-, or
spray-applied at the application rates noted in Table 1.
The ambient temperature must be at least 50°F (10°C)
during coating application, and above 32°F (0°C) for the
24-hour period after application. The coating must not be
applied when dew, condensation, precipitation or freezing
temperatures are anticipated prior to completion of the
coating application. The application of primers, when used,
must be in accordance with the spray foam roofing
manufacturer’s installation instructions.
4.6 Thermal Barrier:
The classified roof assemblies noted in Table 1, containing
BASF Corporation FE348-2.5, FE348-2.7, FE348-2.8 and
FE348-3.0 and ELASTOSPRAY 81255, 81275, 81285 and
81305 foam plastic insulation are recognized for use
without a thermal barrier based on testing in accordance
with UL 1256, as set forth in IBC Section 2603.4.1.5.
4.7 Fire Classification:
4.7.1 New Construction: Roof covering systems, as
noted in Table 1, when installed in accordance with this
report, are Class A or Class B roof coverings in
accordance with ASTM E108 or UL 790.
4.7.2 Reroofing: Prior to installation of new roof
coverings, inspection in accordance with IBC Section
1510, and approval from the code official having
jurisdiction, are required. Installation must be over
uninsulated systems only.
4.8 Wind Resistance:
The allowable wind uplift pressures for the coated foam
plastic roof coverings are noted in Table 2.
5.0 CONDITIONS OF USE
The BASF Corporation FE348 Series and ELASTOSPRAY
81000 Series coated foam plastic roof coverings described
in this report comply with, or are suitable alternatives to
what is specified in, the code indicated in Section 1.0 of
this report, subject to the following conditions:
5.1 Installation and application of the coated foam plastic
roof coverings must comply with the code, the report
holder’s published installation instructions, and this
report. The instructions within this report govern if
there are any conflicts between the report holder’s
installation instructions and this report.
5.2 The spray-applied foam roofing insulation must be
applied by installers trained or approved by BASF
Corporation or trained by the Spray Polyurethane
Foam Alliance.
5.3 Where moderate or heavy foot traffic occurs for
maintenance of equipment, or is otherwise necessary,
the roof covering must be adequately protected to
prevent damage or wearing of the surface.
5.4 Foam plastic insulation must be separated from the
interior of the building by an approved thermal barrier
in accordance with IBC Section 2603.4, except as
noted in Section 4.6.
5.5 The allowable wind uplift pressures listed in Table 2
are for the roof covering only. The deck and
supporting structure to which the roof covering is
attached must be designed to withstand the
applicable wind pressures determined in accordance
with ASCE 7.

5.6 Flashing must be installed at wall and roof
intersections, at gutters and around roof openings, as
required by IBC Section 1503.2.
